If you had money to burn, what would you buy? Read on to see the most expensive items ever to sell on eBay.

If you had $1.2 million to burn, what would you buy -- a nice house, a fleet of slick cars, your own island?

How about an unusually small -- and valuable -- baseball card?

That's exactly what collector Brian Seigel did in 2000, when he paid $1.1 million, plus a 15 percent buyer's fee, to acquire the T206 Honus Wagner (PSA 8 NM-MT, to be exact) card. The item isn't only coveted among baseball card aficionados -- it was also the most expensive item purchased on eBay that year.

Experts say the card's "quality, rarity, and legend" make it the most illustrious baseball card on earth.

The record-setting price for lunch with Buffett topped the 2010 winning bid by $100.

Bridgeville, Calif.

Houses in Bridgeville (Credit: AP)Anyone want to buy a town? Bridgeville, Calif., and its 30 or so residents have been on the auction block three times since 2002, when the northern California community became the first town ever to sell on eBay. The winning bid -- $1.77 million. That got you an 83-acre town including eight houses, a cafe, and a post office.

Oh, and a hell of a view. Laguna Hills, Calif., mortgage banker Bruce Krall, who owned Bridgeville from 2004 to 2006, said in an interview with The Orange County Register that in the town "at night, when the clouds roll in over those mountains, it's spectacular."

But being owned is unpredictable -- and potentially tragic. Bridgeville's most recent owner, a 25-year-old college student, committed suicide in Los Angeles in 2006 only a few months after buying the town from Krall for $1.25 million.

Atlas F missile base

An anonymous couple bought the de-commissioned facility, where the Defense Department once housed an intercontinental ballistic missile silo, over eBay in 2002 for $2.1 million.

The complex, build by the federal government during the Cold War era, was designed to withstand a direct nuclear hit. Gregory Gibbons, one of the site developers who listed the property on eBay, described the silo before the auction as the "perfect solution for the right family or corporation," noting the "escalating threat of world terrorism and an increasing need for security." The mountain getaway included its own private airstrip, a Jacuzzi, and the kind of tranquil living space afforded by three-foot thick walls.

An even better preserved Atlas missile-launching facility was listed for sale on eBay in April of this year. "Don't just buy a bunker," reads the listing, "buy a complex that's designed to withstand anything." Jeff Flaningam, the seller of the item and owner of Veritas Forge product development company, set a $300,000 minimum starting bid for the silo, while adding that the site's owner would consider trading the property for a "luxury diesel coach plus cash."

Giga-yacht

And that 405-foot "giga-yacht," built by Frank Mulder of Mulder Design, could've been yours for a measly $140 million.

Listed on eBay in 2005, the yacht came equipped with 10 multi-level suites with panoramic windows, eight guest cabins, a salon, a cinema room, a fitness room, an office area, and your very own mega-laser (OK, we made that last one up.) The chopper garage offered "the ultimate in protection and functionality for your helicopter, to better reach those remote areas," according to 4Yacht Inc.

The winning bidder? Anonymous, of course.

The luxurious Gulfstream II, which seats 12, was sold by business plane vendor Tyler Jet to a charter-flight company headquartered in Africa.

Ian Usher, a British skydiver who sold his "life" on eBay in 2008, said he was a "little bit disappointed" by the winning bid of $309,292.

Precipitating the auction was Usher's marital problems and ensuing midlife crisis. Hoping to clean the slate, he decided to sell all of his possessions. That included a three-bedroom house, parachuting gear, a beat-up Mazda, personal introductions to his friends, and a trial position as a sales assistant at the rug shop where he worked.

Some four years later, the 48-year-old told Britain's Daily Mail in April that he was doing OK. He said he had bought an island in the Caribbean and fallen in love with a Canadian woman. The estimated worth of his new life remains unclear.

'Shoeless' Joe's baseball bat

In 1920, Jackson and seven other Chicago White Sox players were suspended from professional baseball after they were alleged to have thrown the 1919 World Series in what came to be known as the "Black Sox" scandal (despite a court later acquitting him of any involvement in the affair). That ended his career. Jackson's favorite bat, which he used to hit a remarkable .356 over his 13-year career, was a 48-ounce, 32-inch slugger made of hickory. Known as "Black Betsy," it was the only bat he never discarded.

Ferrari Enzo (Credit: Charley Gallay/Getty Images)An Enzo Ferrari supercar, one of only 399 on earth, flew off eBay's lot for just over $1 million in 2004, when a Swiss bidder's winning click beat out the previous bid by roughly $55.

The price-tag set a record for the most expensive item sold over the online auction site in Europe.

In Dubai, where being in debt is illegal, police recently confiscated an Enzo that formerly belonged to a British citizen who had left the car behind after fleeing the country. Cops seized the vehicle after it had baked in the sun for 20 months and collected roughly $27,000 in unpaid traffic tickets. The Dubai police plan to auction the car, which is valued at $1.6 million.
